4. They’re Social Media “Buddies”
If this woman is constantly stalking his Facebook or Twitter page, “liking” all of his photos (except the ones that contain the BOTH of you), keep a close eye on her. If your partner spends an excessive amount of time on social networking sites, observe whether this woman is always on there “keeping him company” or if she’s the reason he’s on them so much in the first place. Social media may seem innocent because it’s all about “friends,” and he may not feel that you have anything to worry about if his page is public. But if you notice that their contact is frequent and flirtatious, it may be time to have a talk with him about blocking her if she crosses the line.
